Electronic control unit calibration

摘要

An electronic control unit (ECU) (102) includes a microcontroller (104), a first non-volatile memory bank (222), a second non-volatile memory bank (220) and a volatile memory (110). The microcontroller (104) is coupled to an external tool (150) and executes a control algorithm, which controls a subsystem (160) coupled to the ECU (102). The first non-volatile memory bank (222) is coupled to the microcontroller (104) and initially stores a plurality of initial calibration tables. The second non-volatile memory bank (220) and the volatile memory (110) are also coupled to the microcontroller (104). The microcontroller (104) executes code, which calibrates the ECU (102) without interrupting the normal operation of the subsystem (160).
